Hihi@ RAILRUAD TIE.

Application filed January 23, 1924.

To all fui/tom it may eminem.'

lie it known that I, Gnonen lV. Sinon, a citizen of the United States, residing at i002 l-lawtlioi'ne-i-1ve-. Baltimore city, in the county of Baltimore City and State of Maryland, have invented new and useful Improvements in Railroad Ties, of which the following is a specification.

lilly present invention has reference to ties for railway rails.

My primary object is to produce a composition tie of a nature which renders the saine strong and durable and which is provided with means for effectively securing the rails thereon.'

1t is a further object to produce a steel tie reinforced by a concrete body, and which includes plates on which the rails rest, continuous longitudinal reinforcing rods passing` through and connected with the plates, other longitudinal reinforcing rods having` 'upset ends terminating` in hooks that are received in depressions in the ends of the concrete body, and whereby gripping surfaces are provided which materially assist in the handling of the tie, while means of a novel nature cla-mp the rails on the rail plates.

lilith the above broadly stated objects in view 'and others which will appear as the nature of the invention is better understood, reference is to be had to the drawing which accompanies and which forms part of this application.

ln the drawing :h

Figure 1 is a side elevation of a tie in accordance with this invention, the rails being clamped thereon, and parts being in section.

Figure 2 is an end view thereof.

Figure 8 is a sectional view on the line BMC-3 of Figure 1.

Figure et is a sectional view on the line l--fi of Figure 1.

Figure 5 is a sectional view on the line of Figure 2.

Figure (3 is a top plan view of one of the rail plates.

Figure 7 isa perspective view of one of the \\'e lges. Figure t5 rail clamps.

Figure 9 is a transverse sectional view talien through the shank of the clamp.

liigure v10 is a transverse sectional view through the moldboi; in which the rein- :torcing concrete body is molded around the .metal portions of 'the tie.

is a similar view of one of the Serial No. $89,329.

rlhe concrete body of the tie is indicated by the numeral 1. Embedded in the upper face, adjacent to the ends of the body, in the process of molding, there are transversely arranged rail plates 2. Each of the rail plates, adjacent its edges, is formed on its upper face with longitudinal slots or channels 3, and the under face of the plates, below the channels is formed with reinforcing ril 4f. The plates 2, at suitable distance ini ward of their ends, are provided with transifersely arranged openings 5, the inner walls of which being rounded. Below these openings there are weldedor otherwise secured on the under face of the plates metal pockets 6. The pocket members may be of thinv and comparatively cheap metal, but the rail plates 2 are of steel.`

Reiieived in the grooves or channels 3 of the ilates 2 there are portions 7 formed by uisetting the upper members 8 of a continuous reinforcing rod. The reinforcing roes are of a substantially rectangular formation, the lower portions 9 being suitably spaced from the upper portions 8, and the connecting ends thereof are curved, as indicated by the numeral 10. As the continuous reinforcing rod is of a length almost equalling that of the body of the tie, and as the said rods are disposed in spaced relation'to each other adjacent to the sides of the tie, the same not only provide an ample anchor for the rail plates 2, but afford an effective reinforcement for the concrete body. In addition to the continuous reinforcing rods there are arranged therebelow, and outwardly therefrom, other reinforcing` rods 11. rlhese rods have their ends upset, as at 12, and their' extremities curved to provide hooks 18. The ends of the tie, in a line with the hooks, are formed with transverse rounded depressions 1l. rlhis construction provides a hand grip whereby the ties may be easily handled. 'The ends 12 of the rods l1 are disposed in close proximity to the outer ends of the concrete body 1 to protect said ends while the hooks are exposed through the depressions 14; and being con nected togetlier, as at 15 (Figures 5 and 10), a metal frame is afforded, the depressed portions of the body, preventing` the breakage thereof.

The openings in the rail plates are spaced away from each other a suiiicient dis-- tante to receive the rails therebetween. The rails are engaged by the upper headed ends 16 of clamps 17. Each of the clamps has a depending shank 18 that terminates in a laterally extending hook 19. The outer portion of the shank is rounded as is one ot the corners thereof, as clearly disclosed in Figure 9 ot the drawings. This permits otl the hook 9 being inserted tln'ough the openings 5 and the shank 18 turned to bring the jaw 1G over the base flanges ot the rails, the rounded portion of the shank contacting with the inner rounded walls provided by the openings 5. T he aws 1G are notched, as at 20, in a line with the outer flat faces of the shanks, and received through this notch for lrictional engagement with the straight side of the shank and with the straight walls provided by the openings 5, there are wedge members 21. `Each of the wedge members has an otl'set head 22 that is normally positioned above the tie plates 2, so that an implement, such as a bar, may be inserted therebeneath to remove the wedge. The jaw has its edge, opposite that provided with the notch, formed, on its lower corner with a longitudinal groove 9A.

The manner in which the construction is molded is illustrated in Figure 10 ot the drawings. It will be noted that the plates 2 are arranged upon the bottom of the mold and that the reinforcing rods are held in pre1 er spaced relation by wire elements 25. It will. be noted that the wirel elements are otl'set at the portions thereof that rest on the inner continuous reinforcing rods and likewise otl'set to underlie and support the outer and what may be also called the continuous reiniiorcing rods. The plastic concrete is poured in the mold, and as the mold box has its sections removably connected, the tie may be easily removed therefrom when the plastic body is hardened.

Having described the invention, l claim A railway tie comprising a plastic. body, rail plates em edded in the top thereof, a continuous reinforcing rod having rounded corners and ol'set portions which pass over the plates and which are secured tin-meto, the rod being embedded in a concrete body, other reinforcing rods disposed below and. outwardly oi the first mentioned rod, the ast mentioned rods having upset ends terminating in hooks which are connected together and the ends of the tie at the hook portions ot the rod having transverse depressions therein.

In testimony whereot` I atlix my signature.
